Arsene Wenger has confirmed Aaron Ramsey, Jack Wilshere and Mikel Arteta are out for the next week, meaning the injured trio will miss Arsenal's Champions League match against Galatasaray on Wednesday.

All three are likely to be absent for Arsenal's Premier League clash with Chelsea next Sunday after picking up injuries during the 1-1 draw against Tottenham Hotspur at the Emirates.

Wenger said: 'I don't know how long they will be out but they will be out next week. I think Ramsey is a hamstring (injury), and Arteta is a calf. Wilshere is an ankle.'

Wenger admitted he does not know whether Wilshere will return for Chelsea, but said: 'The two other players are out for Chelsea, for sure.

'Suddenly, we are short because if we lost three players today, and let's not forget we had already two out on long-term (Olivier Giroud and Mathieu Debuchy) plus (Theo) Walcott, that's six. (Abou) Diaby is not ready, seven. It starts to become a worry.'

Asked if he was worried by the amount of injuries Ramsey and Wilshere suffer, Wenger replied: 'Not constantly. Wilshere - if you see the incident, he has been tackled and brought his ankle over.

'Ramsey - yes, it's a concern. He had a good rest this week, I didn't play him against Southampton on Tuesday night, it's a surprise because he's usually a resistant boy.'

Alex Oxlade-Chamberlain salvaged a point for Arsenal with a 74th-minute equaliser in the 176th north London derby after Nacer Chadli gifted Tottenham the lead early in the second half.

And the England international was glad to nab his first goal since February.

'Obviously going 1-0 down in the Spurs derby is always a bit nerve-wracking because you never want to lose the game,' Oxlade-Chamberlain told Sky Sports 1.

'I thought we did well to come back, but once we made it 1-1 I really thought we could push on and get the winner. We knew first and foremost that we had to compete with them and that's what derbies can be like and sometimes it's not the best football, it's who wants to win it more.

'I think that was a bit of the case in the first half and I think we came back in the second half. The nerves settled down a bit and we started to pass the ball better and we started to get into the game more.'
